Eastport, Me., at low-water mark. Specimens dredged at many lo- 
calities, in 3 to 21 fathoms, from Block Island to Halifax, Nova 
Scotia, appear to belong to this species.

Dendronotus robustus Verrill. 
Dendronotus robustus Verrill, Amer. Journ. Sei, vol. i, p. 405, fig. 1, 1870; Proc. 
Nat. Mus., ii, p. 197, 1879. 
Dendronotus velifer G. O. Sars, Mollusca Reg. Arcticee Norvegize, p. 315, tab. 28, 
fig. 2, tab. xv, fig. 4 (dentition), 1878. 
The species well described and figured in the excellent work of Sars 
is identical with the American form. Our D. robustus was described 
from a specimen not fully grown; but we have since dredged it of 
larger size, agreeing with D. velifer, in numerous localities, Vineyard 
Sound to Nova Scotia, low-water mark to 98 fathoms; and south of 
Martha’s Vineyard, station 869, in 192 fathoms. The dentition of 
our original specimen is like that of D. velifer figured by Sars.
